SpaceX Will Use Tesla Car Batteries to Power Movable Wings for Starship Re-Entry

SpaceX installed battery packs equal to the batteries used in four Tesla Model X cars to power the movement of wings on the SpaceX Starship. Moving the wings will enable the Starship to generate lift during re-entry to lower the peak temperature. This along with lightweight reusable tile heatshields will prevent damage during re-entry.

Elon Musk will present the new SpaceX orbital Starship design on September 28.

Many powerful electric motors & batteries. Force required is enormous, as entire fin moves. More about this on the 28th.

Exactly. For reusable heatshield, minimize peak heating. For ablative/expendable, minimize total heat. Therefore reusable like Starship wants lift during high Mach reentry for lower peak, but higher total heat.

Better just to ride your max temp all the way down & let T^4 be your friend. Lower atmosphere cools you down real fast, so not crazy hot after landing.

Could do it, but we developed low cost reusable tiles that are much lighter than transpiration cooling & quite robust
